The m+p international Newsletter is circulated exclusively to test engineers and managers involved in vibration test, data acquisition and signal analysis and hopes to bring you some useful technical snippets gleaned from around the world and from around the test and measurement industry. We always look forward to your inputs, send us your views to
1. m+p SO Analyzer Selected for Structural Dynamics Research Continuing our past successful collaboration with top university research laboratories, Customers doing structural dynamics testing have the unique ability with the SO Analyzer to utilize National Instruments or VTI Instruments E143X series front-ends along with the new VibPilot. This maximizes existing resources and gives the customer freedom to expand picking the right hardware to use with no changes in the software.
The University of Illinois, the Purdue University, the University of Connecticut and the New Mexico State University recently selected m+p SO Analyzer software together with the VibPilot front-end for structural dynamics research.

Astrium Selects VibPilot for Vibration Testing of TEXUS/MAXUS Sounding Rockets In Trauen/Germany, Astrium manufactures parts of the TEXUS and MAXUS sounding rockets for microgravity research in biology, materials science and physics. Astrium operates missions with sounding rockets on a commercial basis, as prime contractor to ESA (European Space Agency) or the German Aerospace Centre (DLR). These rockets for scientific experiments under weightless conditions are launched from Esrange in northern Sweden. During the parabolic flight of the rocket, data is obtained either by telemetry or after recovery of the payload. The scientists can control the experiments directly as they are operated by means of telecommand and video streams. Astrium, Trauen, operates four test stands to meet a wide range of test requirements. For vibration testing Astrium has been using m+p international’s proven VibControl shaker control system for many years. Now they replaced the existing measurement hardware by 3. m+p international at IMAC Conference and Exposition on Structural Dynamics Please visit m+p international at the IMAC-XXIX Conference and Exposition from We would also like to invite you to the paper that Tim Copeland, m+p international’s Central Region Manager, and staff members of the University of Illinois will present on Monday Nonlinear Modal Identification Techniques Reveal Nonlinearity in a Dynamics Benchmark System (Paper 198, Session 11) This paper applies several techniques to analyze a dynamics benchmark system with controlled nonlinearity. Several features in the normal mode tuning approach are used to identify nonlinearity, which can be introduced in a controlled manner in the benchmark system. Response to impact and ring down excitations in the time domain is also gathered and post processed using Wavelet Transforms and Empirical Mode Decomposition to analyze the same dynamic structure with controlled nonlinear behavior. The result is to show how these techniques can first identify and then be used to quantity the nonlinearity. Utilizing the nonlinear dynamics benchmark system presented previously allows controlled introduction of varying degrees of nonlinearity. Well, that brings to a close this edition of the m+p international Newsletter. If there are items of info you would like to see here or if you have useful tips for the rest of the environmental test world, then please send us your pointers and we'll include them in the next edition. Please forward this Newsletter to your colleagues if you have found it of interest, spread the word... With regards, m+p international listens to customers...
